The document discusses the relevance of cell size, focusing on the surface area to volume ratio. It compares cells from animals of different sizes, illustrating how relative sizes remain consistent despite overall animal size differences. Calculations are provided for various cube dimensions to highlight the differences in surface area and volume ratios.

1. Does Cell Size Matter?
The Basic Cell
What is surface area
to volume ratio?
Even in a larger animal all cells are the
same relative size as a small animal
